WILLIAM P. MARSH, or DAYTON, orno.

ROTARY Moron.

Specification of Letters Patent. Application filed January 16, 1907. Serial No, 352,587.

Patented April 1 6, 1907 To all whom it maty concern:

Be it known that 1, WILLIAM P. MARSH, a citizen of the United States, residing at Dayton, in the county of Montgomery andaState of Ohio, have invented certain new and useful Improvements in Rotary Motors, of which the following is a specification. 2

My invention relates to improvements in motors, and particularly to rotary engines or turbines.

The motor herein described is especially tion especially adapted to motors of small size and adapted to conditions where high horse-power is not required.

With the aboveprimary and other incidental objects in view, as will appear from the specification, the invention consists of the means, mechanism, construction, and

. mode of operation or their equivalents hereinafter described, and set forth in the claims. Referring to the drawings, Figure 1 is a longitudinal vertical sectional view of the assembled machine. Fig. 2 is a transverse sectional view on line X X of Fig. 1. Fig. 3 is a reverse view of the rotor-disk shown in Fig. Fig. sis an edge view of said disk, partly broken away. Fig. 5 is a detail perspective view of a portion of the rotor-disk. Fig. 6 is a perspective view of one of the curved vanes. Fig. 7 is a detail perspective view of a portion, of the assembled rotor. Fig. 8 is an elevation of the speed-reducing mechanism. Like parts are indicated by similar characters. .of reference throughout the several views.

In the drawings, 1 is the casin cylindrical inform, having a shaft 2 extending through-' out and mounted in suitable bearings 3 and 4 ,in the respective heads of said case. The

bearing 3 is preferably a closed hearing, as

shown. Adjacent to the bearing is a stuffflange 13 within the rotor. secured in its adjusted form by bolts 22 passing-box 5.. Mounted on the shaft 2 and rotating within rings 7 and 8 are a primary rotor 9 and a plurality of secondary rotors 10.

The rotors'are similar in construction, and a description of the primary rotor Wlll sufiice for all. The rotor comprises two parallel disks 11 11, mounted on the shaft 2. disk has an inward-projecting flange 13, having an interior annular recess 14 and a peripheral rabbet 15. The adjacent faces of the flanges 13 have curved slots or recesses 16, asv

in Fig. 5. A series of curved vanes 17 are interposed between the disks 11 11, with the recessed portion 18 engaging in the slots 16 and the projection 19 projectlng into the rabbet' 15, while the portion. 21 projects beyond the The structure is ing through the disks 11 11, impingjilngthe vanes 17 between the disks; By t 'sconstruetion there is formed a hollow rotor having peripheral inlet-ports intermediate the curved vanes 17. Outlet-ports 23 are provided in each of the disks 11 of the primary rotor, but in only one disk of the secondary rotors, as indicated, the disk 12 of said sec ondary rotors being devoid of such outletports. The outlet-ports 23 are arranged in a direction diagonal to, the axisof the rotorthat is, they are arranged'tangent to a com- Each mon circle concentric with the shaft 2 and are likewise inclined longitudinally with said shaft, as shown in Figs. 3- and 4. In the drawings, the disks 11 are shown with a series' of serrations or notches 6. These notches 6 are not essential, but facilitate the location and drilling of the outlet-ports 23.

The case 1 has an inlet 24 for actuatin mediumsteam, gas, water, or compresse air. The inlet 24 communicates with an annular groove or conduit 25 in the ring 7. The ring 7 is further provided with a series of discharge-orifices 26, tangent to a common circle and located in a vertical plane with the vanes 17 of the rotor. The arrangement 1s such that the actuating medium will be directed upon the periphery of the primary rotor, striking the vanes 17, will cause the rotor to revolve, and will be discharged, through the vanes to the interior of the rotor. The medium will find outlet from the rotor through. c

'fwould reduceits velocity.

medium will be given direct passage through the r0tor-that' is, the current of medium will not be required to make any" sudden or abrupt change of direction, but \v'ili readily find an outlet in its direct cours of trav'e the object being to prevent gi rent of medium atortuous isage whichv j The vanes 17 areadapted to receive the impact force of the medium discharged through the orifices 26. The outlet-ports exten: outward and rearward in relation to the rotation of the rotors, and thus the medium escaping through said ports exerts a recoil force on the rotor adapted to accelerate the speed.

The rings 8 of the secondary rotors are flanged as at 27, having their open side towar the primary rotor. The flange 27 is provided with orifices 28, similar to those 26 of the ring 7; From the primary rotor the steam passes into the case 1 intermediate the rotors, thence through the orifices 28 of the flange 27 to the vanes of the. secondary rotor 10. l

While in the drawings but one secondary rotor is shown on each side of theprimary rotor 9., it is to be understood that the series of secondary rotors may he continued to suit conditions,-the medium passing through. the secondary rotors successively. From the last secondary rotor of the series the medium is discharged into case 1 and is conducted thence through. outlet-pipes 29.

It has been found by experiment that the velocity of the rotors and shaft 2 will be too great for practical use. A speedareducer is therefore provided. (hi the extremity of the shaft 2 is a pinion 3U, moshing with the greater step of several stepped gears 31,- mounted on a revoluhloplatc or head '32. 'lhesmaller steps (if the gears 31 hnesh with an internal stationary gear 3 A driven shaft 34 is secured to the. head 3 The construction is such that the gears 31,- driven by the pinion 30,\v ll travel about the interior of the gear 33, revolving the. lit-drift? and therewith the shaft 34 at a reduced speed.

From the above description it will be apparent that there is provided a rotary engine possessingtheparticulnr lea tures of advantage before enumerated as desirable and which obviously is susceptible of modification in. its form, proportion, detail construction, and arrangement of parts u'itimnt departing from the principle involved ire-sacrificing any of its advantages.
